LLAMAS?????

today in human Geo we presented our power points that some of us worked on for the past 2 days. there was a lot of interesting things that we learned like what i though was interesting was that there where 20 to 30 million people in america before Columbus got here. i had always thought there was like 20 or 30 thousand. i also thought it was weird that the vikings were here first and they dint do anything to try and clame they just really wanted to attack the people
